A 7-year-old, intact female Korean Jindo dog was referred due to ataxia and pain on palpation of the thorax. Radiograph, echocardiography and computed tomogram revealed a mass on the heart base region and osteolytic change of fifth thoracic (T5) vertebra. At necropsy, a firm, encapsulated and round mass was seen arising from the heart base region surrounding the ascending aorta and pulmonary artery. Histopathologically, nests of cuboidal and polyhedral cells having abundantly granular and eosinophilic cytoplasm with round to oval nucleus were separated by fibrous septa. Immunohistochemistry using chromogranin A revealed that tumor cells were originated from neuroendocrine organ and metastasized into some organs including lung, spleen, liver, kidney and T5 vertebra. By electron microscopy, we found the electron-dense and membrane-bound granules in cytoplasm of the tumor cells. This study provides the uncommon evidence that aortic body tumor metastasized to both multiple organs and bone.

Compared to the other chemodectoma, aortic body tumors, the carotid body tumor is rarer and more often malignant. In the present case, a 12-year-old, intact female Shih-tzu dog presented to the hospital with a right ventral cervical mass. The mass was diagnosed by immunohistochemical staining with chromogranin A (CgA) as a carotid body tumor. The cervical mass and metastasized lymph node were removed by surgical resection. Because the dog had valvular heart disease, chemotherapy with carboplatin was initiated over 6 months to prevent metastasis and recurrence as an adjunctive treatment. After over two years of management, tumor metastasis and recurrence were not observed until recently. This report shows that proper management and chemotherapy as an adjunctive therapy can treat carotid body tumors in elderly dogs with concurrent heart disease.

12살령 중성화 수컷 페키니즈 개가 허약, 운동불내성과 2주전부터 시작한 기침을 주증으로 내원하였다. 신체검사에서 좌측 수축기성 심잡음(grade II/VI) 이 확인되었고, 심장초음파 검사에서 심낭수와 좌심방 주변 심기저부에 종괴가 관찰되었다. 심낭수천자 후에는 흉부방사선 상에서도 좌심방 옆으로 종괴가 확인되었다. 사후 부검을 통한 조직학적 검사 및 면역조직화학 염색을 통해 대동맥체 종양으로 진단되었다. 본 환축은 진단 후 내과적 치료만을 받았으며, 심낭수의 재발 없이 234일을 생존하였다.
